Waitlister

Create a new waitlist on your Waitlister account (requires an account key, works on every plan within its waitlist cap). Returns the waitlist key and a form_action_url that collects signups immediately. Pass landing_page to also provision the hosted landing page (as a draft — go live with publish_landing_page) in the same call. Note: waitlist names and URL slugs are unique across all of Waitlister — a taken name/slug is rejected with guidance to pick another.

Check the configured API key and what this account may do — the cheapest first call, and the one to make when anything looks misconfigured. Returns the account, the plan name, whether the general API is available, how many waitlists the account has against its cap, whether creating another would succeed right now (can_create — a true dry run, so check it before create_waitlist rather than discovering the cap from an error), remaining AI credits, and the key's name/created/last-used. An invalid or revoked key fails here cleanly, which distinguishes a dead key from a malformed request. Requires an account key (wl_acct_…) and works on every plan. Never returns the key itself.

List every waitlist your account owns, with subscriber and view counts (requires an account key).

Get a waitlist's subscriber and view counters — cheap social proof, works on every plan. Counters update asynchronously (within seconds of a signup or delete).

Add a new subscriber to a waitlist. Returns their position, referral code, and sign-up token. Idempotent per email: an existing email returns is_new_sign_up: false with their current position, not an error. Works on every plan.

Retrieve a paginated list of a waitlist's subscribers, sortable by position, points, date, referral_count, or email. Requires the Growth plan or higher.

Retrieve detailed information about a specific subscriber by their ID or email address — position, points, referral info, metadata, location, and more. Requires the Growth plan or higher.

Update an existing subscriber's name, phone, points, and/or custom metadata. Only include fields you want to change; updating points triggers a queue position recalculation. Requires the Growth plan or higher.

Permanently delete a subscriber (and their email history) from a waitlist by ID or email address. This cannot be undone. Counters and queue positions update asynchronously within a few seconds. Requires the Growth plan or higher.

Record a view of a waitlist page — useful for tracking engagement and conversion rates when you host your own landing page.

Get the structured view of a waitlist's hosted landing page: status (draft/published/unpublished), page_type (standard or ai), copy fields, theme, SEO, the live URL (null until published), and view/signup analytics. AI-built pages also return remaining AI credits. Works on every plan. 404 if the waitlist has no page yet — create one with create_landing_page.

Create the waitlist's hosted landing page from structured fields, as a draft (nothing goes live until publish_landing_page). One page per waitlist — returns a 409 error if one already exists (use update_landing_page then). headline is required. Works on every plan. Tip: when creating a new waitlist AND its page, use create_waitlist's landing_page parameter instead — one call.

Update any subset of the landing page's structured fields. On a published page the change goes live immediately. IMPORTANT: on an AI-built page (page_type "ai"), the copy/structure fields (headline, description, button_text, collect_name, collect_phone, background) return a 409 error — edit those with generate_landing_page and is_edit: true; theme and seo still work here on both page types. Works on every plan.

Publish the landing page to its live URL (https://waitlister.me/p/{slug}, or the waitlist's custom domain) — or take it offline with unpublish: true. Publishing validates the page has an email field, a submit button, and a headline of at least 3 characters. API publishes skip the custom social-share (OG) image; publishing once from the dashboard generates it. Works on every plan.

Generate a complete custom landing page from a natural-language prompt with Waitlister's AI builder (same engine as the dashboard), or edit the existing AI page with is_edit: true. COSTS 1 AI CREDIT per call (shared with the dashboard AI builder; errors with the balance when out of credits) — don't call repeatedly for small tweaks a human should review. Synchronous, typically 20-50 seconds. The result is saved as a draft: review in the dashboard or go live with publish_landing_page. The AI conversation is saved, so the dashboard's AI chat continues where this left off. After generating, the page is an AI page — see update_landing_page for what that changes.
